I travel through time by one second every second.
I travel through time by one nanosecond every nanosecond.
Actually, due to the effects of velocity time dilation, and gravitational time dilation, for every 1 second that passes for me where I am on earth ~1.0000021691582424 seconds pass for someone at relative rest, and free from a gravitational field.
Velocity time dilation is given by: 1/(sqrt(1-v^2/c^2))
Where
v is the current velocity (~1,913,285 mph for my location on earth)
And
c is the speed of light
Gravitational Time Dilation is give by: t(o)=t(f)*sqrt(1-r(0)/r)
Where:
t(0) is the proper time between events A and B for a slow-ticking observer within the gravitational field,
t(f) is the coordinate time between events A and B for a fast-ticking observer at an arbitrarily large distance from the massive object
r is the radial coordinate of the observer
r(0) is the Schwarzschild radius of M (r(0)=2GM/c^2)
G is the gravitational constant
M is the mass of the object creating the gravitational field
